HENRY WEGMAN, or ITHAOA, NEW YORK.

M ECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 251,977, dated January 3, 1882.

Application filed September 17, 1881. (No model.)

7 To all whom it may concern:

Be it known that I, H. WEGMAN,of Ithaca, in the county of Tompkins and State of New York, have invented a new and useful Improvement in Mechanical Musical Instruments, of which the following is a full, clear, and exact description.

Myinvention relates to musical instruments in which strips of perforated material are used for governing theadmission of air to the reeds and pipes; and it consists in the novel construction hereinafter described and claimed, by means of which the reeds and pipes can be operated singly andin combination with the same perforated paper.

Reference is to be had to the accompanying; drawings, forming part of this specificatiomin which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is avertical section of my improved musical instrument, and Fig. 2 is a vertical section on line 00 x of Fig. l.

A is an air-chamber, fitted inits lower portion with bellows B,b'y which air is compressed in the chamber.

0 is an air-tight cover, held in place on the chamber by buttons (1, which permit removal ofthe cover.

D is an apertured reed-block fixed on the cover 0, and carrying reeds b'and pipes c.

d is a block attached to the under side of cover 0, and apertured to correspond with block Dand the several pipes and reeds theree is a similar block, sustained by springs f in chamber A, and pressed by such springs against the under side of block d.

In chamber A are rollers g g, sustained in suitable bearings and h h are similar rollers sustained from cover 0, so as to bear on the rollers 9. One roller, g, has acrank-handle, t,

on its axis, outside the chamber, and there a connecting-rod, 70, from the crank passes to the bellows B. The perforated sheet or strip of paper shown at 1 passes between rollers g h and blocks 01 c. It is applied by removing the cover 0, which leaves the rollers g and block a exposed.

In operation the handle I is turned,and the perforated sheet being thus fed between the blocks 01 e. the air passes to the reeds and pipes through the blocks Ddwhenever a perforation of the paper comes beneath the aperture of block (1. Each perforation admits air to one reed and one pipe, and by suitable arrangement of the perforations any desired combination can be effected. The springs f press the block 0 on the perforated sheet, and thus prevent passage of air except by the perforations.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- 1. The combination of air-chamber A, containing feed-rollers g and apertured block e, with cover 0, apertured block D, carrying reeds and pipes, apertured block d, and the feed-rollers h, secured to the under side of cover 0 ,substantially as shown and described.

2. The removable cover 0, carrying reedblock D, apertured block (I, and rollers h, combined with the air-chamber A, block 0, and rollers gin the chamber, substantially as shown and described.

3. The springsfand apertured b1oeke,supported upon said springs, combined with the stationary paper-rollers g and removable rollers h, and apertured block 01, all arranged to operate substantially as shown and described.
